Question

a train travelling 67.5km/h passes a pole in 9 seconds and a platform in 29 seconds. what is the length of the platform?

Answer 1

Answer:

The length of the platform is 375 m.

Step-by-step explanation:

Hey Mate ,

67.5 km/ h = 1.125 km/ min = 18.75 m/ sec

Length of the train can found by taking the time in which the train passes a  pole = 9 × 18.75 = 168.75 m

Let length of platform be X

So 18.75 × 29 = (168.75 + X )  

Solving we get X = 375 m

So,

The length of the platform is 375 m.
